They are among us no, not aliens, but Nokia 9 prototypes. Someone was spotted in Jakarta testdriving the phones alleged Dual 13MP camera.
You can see the vertically-oriented dual camera on the back. With the LED to the side, it matches the design we saw leaked by a case maker.
The front allegedly sporting a 5.5 OLED screen with a tall 18:9 aspect ratio is less clear. There have been rumors of rounded sides and it kind of looks like that is the case in these images.
There is a chance that this is a Nokia 7 Plus instead, which features a similar design and spec sheet. Either way, we hope to find out at the MWC HMD promised awesome stuff.
